POWR-FLITE PREDATOR AUTOMATIC SCRUBBER 20
This manual refers to a battery powered automatic floor scrubber. Designed to be simple, easy to operate and safe, with maneuver-
ability and automatic variable electronic drive. Routine maintenance has been simplified and reduced to the minimum to keep
equipment on the job.
- 2 -
The floor cleaner is intended for cleaning and washing level
floors in closed spaces using appropriate detergents. This man-
ual serves to guarantee the correct use of the machine thus sup-
porting the service that we offer the customer. You are advised
to adhere strictly to the instructions contained in this manual
since the manufacturer does not accept responsibility for any
damage caused to persons or to property, or to the machine
itself if it is not used in the way described here or if the safety
and maintenance instructions are not followed. The instruc-
tions set out in this manual do not substitute the safety mea-
sures and technical specifications to be applied directly to the
pro-duct for installation and operation, nor the safety regula-
tions in force in the country where it is used or the rules of
common sense.
The installation or maintenance personnel must report any
defects or deterioration, which might compromise the safety of
the machine.
The personnel responsible for operating the machine must have
specific professional training or must have experience of using
machines of this type.
In order to prevent damage to people or to property, we advise
the customer to instruct adequately the operators on any risks
related to the use of this machine. The operator must always
make use of the protective measures prescribed by the laws of
the country in which the machine is used as well as additional
protection provided by the employer (safety shoes, overalls,
safety glasses, etc.).
The responsibilities of the personnel authorized to use the
machine are at the discretion of the customer.
Maintenance personnel must have the specific characteristics
(maintenance technician) necessary for correctly interpreting
diagrams and instructions.

Powr-Flite declines all responsibility for damage of any kind
resulting from imprudent use by expert or inexpert personnel
who have not operated the machine in accordance with this
manual. The installation must be carried out in accordance with
the laws in force in the country where it is installed; Powr-Flite
is not responsible for equipment upstream of the cleaner.
The customer must use exclusively original spare parts and fit
them in the intended way. Responsibility deriving from other
commercially available components rests with the customer.
Do not leave any objects of any kind on the floor as they may be
thrown at high speed by the brushes.
Keep feet and hands clear of the moving brushes.
Ensure that the main power key switch is in the OFF position
and that the batteries are disconnected before carrying out any
maintenance and/or filling the tanks with detergent and/or
changing the brushes.
Maintenance procedures must be carried out by authorized
personnel.
Do not carry out any un-safe or temporary repairs or use
non-original spare parts.
Regularly check the wear and deterioration of the materials
and, if necessary, call out your regular supplier.
When working near the batteries use protective glasses and
clothing. Remove any metal object.
Do not rest metal tools or equipment of any type on the
batteries.
Recharging the batteries produces explosive gas.
DO NOT SMOKE,
LIGHT FLAMES OR
MAKE SPARKS.
Ensure that the charger is switched off before disconnecting it
from the batteries. Recharge the batteries in a well ventilated

Diagram 1

If the cleaner is left unattended remove the key from the main
power switch.
Do not leave the cleaner unattended particularly if children are
present. Do not use or install the cleaner in places where flam-
mable gases or liquids are present. Do not use flammable liq-
uids or chemicals with this cleaner. Ensure that the instruction
manual and warnings are always to hand and are legible.
Replace any torn or missing pages.
This machine must only be used on flat and level surfaces.
DO NOT USE IT ON INCLINED SURFACES without the assis-
tance of the appropriate personnel.
Do not operate the machine in bare feet, with sandals or any
kind of open footwear.
Do not wet electrical components with water or any other liq-
uid. Dry the machine with a cloth.
Powr-Flite is not responsible for the disposal or production of
products necessary for its operation; e.g. batteries, detergents,
etc.; the customer himself must, therefore, arrange for the dis-
posal of sub-stances harmful to the environment in accordance
with the laws of the country in which it is used.
N.B. The same precautions should be taken when the machine
is scrapped.
The machine generates a sound pressure level (noise) in an
industrial environment (warehouse/ shop floor) which is less
than 80 dBA and is therefore absolutely harmless for the opera-
tor. However, in other surroundings, this level may be exceeded
in which case the customer must provide appropriate protec-
tion (ear defenders) as well as notices to promote their use and
periodic hearing examinations.
The operator must not wear clothing with wide sleeves, laces or
belts; he must not approach the machine with bare or wet feet;
he must not pull out the plug by pulling the cable; must not
smoke if the environment or products used do not allow it.
For lifting and transporting use only specialized personnel
(slingers, crane operators, etc..) with proper lifting gear which
is suitable for the weight of the various components.
- Transport (especially by road) must be carried out with in the
correct way and with the adequate means so as to protect the
components (especially the electronic ones) from violent
shocks, humidity, vibration, etc..; the machines are supplied
with wheels and therefore need to be securely anchored before
beginning transportation.

We remind you that packing material (wood, nails, paper, cello-
phane, metal staples, adhesive tape, straps, ropes, etc.) may cause
cuts or wounds and should be handled with care. These must be
removed with appropriate tolls and should not be left in the care
of irresponsible people ( e.g. Children); the same applies to the
un-packing tools (scissors, hammers, pliers, knives, etc..).
On specific request, Powr-Flite will pack the machines appropri-
ately but this does not eliminate the above safety notes.
N.B. During movement, suspended loads made up of machine
components or parts represent a collision, risk, it is the responsi-
bility of the customer to highlight this danger.
WARNING: before attempting to adjust or prepare the machine or
to fill the tanks, make sure that the power supply is disconnected.
Detergent Tank: The detergent tank is positioned underneath
the upper cover at the front of the ma-chine with the filter hole
M1 easily accessible for easy refilling. N.B.: before filling the tank
with correctly diluted detergent, empty the waste collection tank
as described in the following paragraph; obviously this step is not
required for the first time of filling. The capacity of the detergent
tank is 17 gal. only use the quantities and dilution recommended
by the detergent supplier and use only non-foaming detergents.
Waste Tank: The waste tank should be emptied (preferably after
each use) so as not to let the dirt settle; to do this, remove the
cap covering the drain tube M2 which is held in place by a retain-
ing spring, and put in a position so that it drains. Always abide by
the environmental regulations of the country where the machine is
used.
Wiper Blade: The floor wiper serves to finish the drying opera-
tion and it is very important to ensure it is in the correct position:
lower the wiper to its working position using the foot pedal M3;
level the wiper using the knobs M4 so that the black rubber strip
is approximately 1 mm above the floor.
The remaining para rubber strips must wipe the floor with a cer-
tain amount of pressure; after the first few hours of operation the
rubber wipers adapt themselves to the inclinations and the drying
action improves. The pressure of the wipers on the floor is regu-
lated by pressing the knob.
When cleaning shiny or smooth floors and when there are holes
(joins between tiles) it is advisable not to use the rear (lowest)
rubber wiper.
Installing and recharging the batteries: The batteries are supplied
separately and are located in the appropriate compartment under-
- 5 -

- 6 -
neath the cover; apply a coating of grease (e.g. Vaseline) to the
terminals; connect the batteries as shown in diagram 1; make
sure the terminals are securely tightened. The battery charger
should be set up in the area where it is planned to leave the
machine for recharging. Use the cable supplied to connect to the
mains supply, normally 120 V 50 Hz; make sure that the supply
voltage is the same as indicated on the battery charger itself. To
charge the batteries connect the connector M5, which comes
directly from the battery compartment, to the battery charger con-
nector. The charger will automatically regulate the charging cur-
rent and will turn itself off when the batteries are recharged.
WARNING: The battery acid may give off harmful fumes. When
working near the batteries use protective glasses and clothes.
DO NOT PLACE ANY METAL TOOLS OF ANY KIND ON THE
BATTERIES. Recharging the batteries generates explosive gas. Do
not smoke, light flames or make sparks. Make sure the charger is
switched off before disconnecting. Recharge the batteries in a
well-ventilated area and keep the cover open.
WARNING: objects lying on the floor can be thrown at high speed
by the brushes, endangering people and/or property.
The area to be cleaned: In order to increase the effectiveness of
the detergent, the area to be cleaned should first be swept (manu-
ally or by machine) to remove loose dirt, which may quickly clog
up the suction circuit.
Powering up and operation:
• Turn off the battery charger and disconnect it from the
machine. Connect battery cable to machine.
• Turn the key switch, M6, to position 1 and press buttons M7
and M8;
• Lower the brush by pressing pedal M9;
• Lower the floor wiper by pressing pedal M3;
• Regulate the flow of detergent to a minimum using knob M12;
• Press lever M10, the machine will go forward, keep press the
button M5, the machine will go back-ward. Releasing M10
to stop the machine
• Regulate the forward speed with potentiometer M11;
• Finally, use lever M12 to regulate the dosage of detergent
according to the amount of dirt and the speed of the machine.
Particularly dirty floors: Certain floors or environments require
particular attention or even a second pass with the cleaner.
In this case you should make on pass with the wiper raised and
the brush in the working position; in this way the detergent
remains on the floor for longer and will dissolve the tougher dirt.
The second pass should be made with the brush and wiper low-
ered and at a slower speed.
WARNING
this machine is designed to work in closed industrial environ-
ments on level floors or on inclines no steeper than 2%. Do not
use flammable chemicals and/or explosives with this machine.
Floor wiper: Inspect and clean the floor wiper weekly and make
sure to restore it to its working condition. If the drying action
is not perfect after cleaning the wiper assembly, remove and
replace any worn rubber blades.
Brush: The brush must be kept in working order; to remove a
worn brush proceed as follows (follow the procedure in
reverse to reassemble):
• Turn off the machine (key switch in OFF position) and lift the
brush with the pedal provided (M9);
• Release the catch M15 and remove the rubber spray guard;
• Turn the brush to be re-moved by hand until the coils of spring
M19 are accessible;
• By closing together the coils of spring M19 with your fingers
(as if you where closing a pair of scissors) the brush will
free itself;
Waste Tank: clean the tank every week as follows: lift the cover;
remove the cover of the suction motor M1; remove the motor
stop ring M13 and remove the suction motor from its seat;
carefully clean the filter, net and sponge, and remove the dirt
which has accumulated in the tank.
Batteries: Check the electrolyte level and top up with distilled
water if drops below the level of the battery elements. Keep the
batteries clean and dry with anti-static cloths. Recharging must
be carried out with the cell plugs removed and the cover of the
machine opened so as to allow the gases generated to escape.
In confined spaces these gases can be explosive, so recharging
should be done in a well ventilated area.
